The Dwarven Set consists in all dwarven equipment. It can block 10% of Physical Damage.
A Helmet of the Ancients could also work because it has the same color scheme as the armor and legs.
Wearing all pieces of this set with physical protection can be as good as wearing a Demon Helmet, Magic Plate Armor, and Golden Legs but only if you fight Creatures with physical attacks higher than 252 and using no shield. So you will have to fight stronger monsters to make this set better than a Rare Set.
